Atone
Read full descriptionHide full description
You decide how hard your limit holds. Atone gives your worst apps a daily limit and blocks them the moment it runs out. How strictly that block holds is yours to set before the first day begins - including whether money is part of it at all. HOW IT WORKS 1. Seal the promise. Pick the apps that take your day and set how many minutes they get. 2. Choose how hard the limit holds. Three ways, see below. 3. Live the day. Those apps work normally until the minutes are spent. 4. Then they stop opening. The lock screen shows what you wrote when you were still clear-headed. THE THREE WAYS No way past it. The apps stay shut until midnight. No exception, not even for you. Wait and write. Going on takes a hundred seconds of waiting and a reason you type out yourself. No money. Put money on it. A written reason, no waiting, and an amount you named yourself beforehand. WHY WAITING AND WRITING WORKS A five-second delay is something you learn to click through. A hundred seconds is not - an impulse does not last that long. And having to write down why it has to be now often shows you how thin the reason is. Whatever you set is sealed for the day. Changes take effect tomorrow, never now, because the moment you want to loosen the rule is exactly the moment the rule matters. IF YOU PUT MONEY ON IT The stake is not a price for more time. It falls due because you broke your promise, not so that you can carry on. What you owe stays owed until it is paid. Atone itself never costs you anything, and neither does a day you hold. Choose a way without money and no card is stored and no payment details are given at all. You can remove your card at any time; your promise then continues without money. Half of our revenue goes to charity. Not half of your stake - half of everything we take in, whether you ever pay a cent. The sums we actually give are published. YOUR DATA STAYS WITH YOU Your promise, your stamps and your history stay on your iPhone. No account, no tracking, no analytics, no ads. Atone is built on Apple's Screen Time framework, which means even we never learn which apps you use or for how long. The reason you type when you go on never leaves the device either. Only if you put money on your promise does a payment provider come into it. Even then it sees a charge, not your day. WHAT YOU GET · A daily limit for the apps you choose · A real block when it runs out, not a gentle nudge · Three ways to set how hard it holds - changeable any time, from the next day · A streak counting the days you stayed within the limit · A weekly view of how the promise went · English and German, on-device, no account Atone does not want your money. It wants you to keep the promise you made to yourself.
CogniShield

Fewer automatic opens. More intentional choices. CogniShield blocks the apps you select and asks you to complete a short challenge before reopening them. Put a moment of thought between an impulse and a tap, whether you are studying, working or making time for something else. A SHIELD YOU CONTROL Choose apps and websites through Apple’s secure picker. Turn protection on or off from CogniShield. Completing a challenge temporarily opens the relevant target, while your other protected apps stay shielded. MAKE THE PAUSE COUNT Choose from math and logic, geography, the living world, and chemistry. Set the difficulty, the number of correct answers required for each target, and the penalty duration after repeated mistakes. Written challenges are available in French and English; other app languages use the English question bank when available. PRIVACY BUILT INTO THE DESIGN Protection uses Apple’s Screen Time APIs, including Family Controls. App selections use opaque tokens. No account is required, and your challenge counters stay on your device. SUPPORT HEALTHIER FAMILY HABITS CogniShield can support conversations about intentional device use. The current app uses individual authorization from the person using the device. Use Apple’s Screen Time parental settings to manage a child’s device: CogniShield does not offer remote parental supervision or guarantee an unbreakable block. MORE CHOICE WITH PREMIUM The free version protects up to two apps and includes math/logic and geography. Premium unlocks an expanded app selection, category protection, all challenge themes, and context-aware difficulty. Existing Premium entitlements can be restored, including lifetime purchases. Choose an annual subscription or a lifetime purchase, subject to availability in your region. Prices and terms are shown in the app. Subscriptions renew automatically unless cancelled in your Apple account settings. Restore Purchases is available in Settings. Pause, think, and choose what you really want to open.

Verdict
The clearest difference is in-app purchases: Atone at none against CogniShield's 1. Atone also leads on iOS requirement (17.0 vs 26.0). On price, update cadence, ads and device support there is nothing between them.
